Addiction

From Age of Intrigue Wiki

This is a challenge. Your character is addicted to something. It could be the thrills of gambling, fighting, duelling or shopping, making your character compulsive about these behaviours, or it could be an addiction to a specific substance such as food, alcohol or Laudanum.

You will be expected to reflect this addiction in your roleplaying, and to devote time and likely money to the satisfying of their addiction.
